Cleaning the MiniPID
FALCO has been designed to ensure servicing is quick and easy:
1.
Before servicing FALCO, set the device to Servicing Mode.
2.
Unscrew the Sensor Cover (
1
) to access the MiniPID (
4
) located in the Sensor Housing.
3.
Remove the MiniPID (
4
) using the MiniPID removal tool (9). Be careful when withdrawing it, d
on’t
twist when the MiniPID is in the Sensor Housing. Only light force is required.
CAUTION
Do not twist the MiniPID (
4
).while it is within the Sensor Housing.
4.
Use the electrode stack removal tool to remove the electrode stack. Hold the MiniPID (
4
) upside
down, the Electrode Stack (
8
) and PID Lamp (
7
) can then be removed.
CAUTION
Ensure the Electrode Stack (
8
)
and PID Lamp (
7
)
falls onto a soft surface such as a piece of tissue. This
will avoid damaging the parts as they fall out and avoids finger contact with the PID Lamp
window.
5.
Clean the PID Lamp using the PID lamp cleaning kit (A-31063)
To clean the PID Lamp:
•
Open the vial of Aluminium Oxide polishing compound. With a
clean cotton bud collect a small amount of compound.
•
Use this cotton bud to polish the PID Lamp window. Use a
circular action applying light pressure to clean the lamp window.
Never touch the lamp window with fingers.
•
Continue polishing until an audible “squeaking” is made by the
cotton bud with compound moving over the window surface
(usually within fifteen seconds).
•
Remove the residual powder with short blast of air from the can
of air duster.
INFORMATION
Contamination of the PID Lamp window
can considerably reduce
the detection capability of the
MiniPID (
4
), even when the contamination is not visible. Cleaning of the lamp should be carried out on
a regular basis depending on the PID Lamp (
7
)
and the environment.
The humidity of the air and contaminants may affect the time required between servicing.
6.
The Electrode Stack (
8
) should be inspected for visible signs of contamination, if contamination can be
seen the Electrode Stack (
8
) must be replaced
.
Reassembly
1.
Lay the Electrode Stack (8) front face down on a clean, flat surface and then screw the lamp (7) down
into the O-ring until it firmly abuts against the front electrode face.
2.
Place the MiniPID (4) body carefully down over the lamp-stack sub-assembly so as not to disturb its
seating within the electrode stack and then push the body firmly onto the face down Electrode Stack
(8) so that both wings engage with the MiniPID (4) body.
